Question

Please help me I was sick today and missed out on class and I don’t understand this question

Answer 1

see explanation

Explanation:

(a)

the 2 angles are vertically opposite angles and are congruent

(c)

since they are congruent , then

7x + 6 = 6x + 18 ( subtract 6x from both sides )

x + 6 = 18 ( subtract 6 from both sides )

x = 12

(d)

then

7x + 6 = 7(12) + 6 = 84 + 6 = 90

6x + 18 = 6(12) + 18 = 72 + 18 = 90
